How to visually distinguish whether it is hot rolled or cold rolled NM450 plate material
The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our NM450 plate material steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge NM450 plate material steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.
When cutting extra thick NM450 plate material steel plates, the cutting speed should not be too fast. Many processing and production industries will encounter such problems, that is, in order to speed up the cutting of extra thick steel plates, many details will be ignored in the process of these process operations, so it is easy to produce waste parts, and some plates NM450 plate material will crack. So when cutting extra thick steel plates, you must pay attention to the speed, which can not be too fast. Low-speed processing can effectively improve work efficiency.
Bridge steel NM450 plate material is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.
Modern steel-making steel purification facilities and advanced quality control methods have been perfected. Rolling steel can be produced according to controlled rolling and controlled cooling, normalizing, and quenching and tempering processes to produce σs 390-685Mpa series products. NM450 plate material, Low alloy high strength structural steel plate has stable quality, good wear resistance and low temperature toughness. It can be widely used in the manufacture of mining machinery, engineering machinery, high-rise buildings and heavy vehicles.
There are various weather resistant steel materials in the world. Their thickness ranges are distinct. For JIS G3125 weathering steel sheet, typical grades are SPA-H / SPA-C, the max. thickness is 16mm. For TBT 1979 weather resistant steel sheets, typical grades are 09CuPCrNi-A / 05CuPCrNi, the max. thickness is 20mm. For EN 10025-5 steel, typical grades are S355J0WP / S355J2WP / S355J0W /S355J2W, the max. thickness is 100mm. The max. thickness for NM450 plate material, ASTM A588 steel plate is 200mm. And the max. thickness for ASTM A242 steel plate is 100mm.
Our company has its own steel plate manufacturing plant, processing plant and steel pipe plant. We can machine the steel according to the NM450 plate material customer's requirements and meet the customer's requirements.
